Miss SA 2017 Demi-Leigh Nel-Peters has set her sights on the Miss Universe crown.

The pageant queen says her preparations for the competition, which is set to take place on Sunday 26 November (venue still to be confirmed), have been well underway since she first took home the Miss SA crown.

The award-winning muso, who attracted media attention when she joined the #FeesMustFall Movement that saw students and sympathisers taking to the streets to fight for free university education last year, says she won't back down until students' demands are met.
